Can you use hot glue in high density foam?

Question

I'm creating a bench and wanted to know if hot glue will damage the high density foam that I'm using?

Answer 1

I would think it would melt the foam. Have you considered "Great Stuff" as an adhesive?

Answer 2

I use Hot glue often in theater, but it will melt most cellular foam. I have had better success using it on the BLUE foam used for construction insulation, but you don't define your use of foam for your BENCH.

I'll assume something, then hopefully be proven mistaken,,,if in fact the foam you mention is to be any part of the actual resting place for a posterior.

In my theater years (40 plus) I use foam to create architectural or natural shapes and designs. That can be created in fact, with a hot glue gun in melting, shaping, scoring, etc. Even HOT GLUE by itself can create lines and raised areas in swirls, etc, that can be painted over. That isn't how I attach the foam to any base material however. I have often used a water based contact cement. It's a kinda pretty aqua color, washes up with water and works very well..

Ok, after all that rambling,,,If the foam you're speaking of is cushioning foam, then it won't be as adversely effected by Hot glue, but that still isn't the way I'd go.

One of the problems with hot glue is its short span of time it stays pliable and viable as an adhesive. Once it leaves the nozzle of the gun it begins cooling immediately, causing the user to work at a slow pace in very defined areas or lengths of each line of glue. If that isn't an issue, I'd still advise against it. It also tends to leave "strings" Spider web kind of attachments that one has to constantly brush away. AND one more then I'll leave you to ponder,,, or ask more. Hot Glue is nearly impossible to remove cleanly, from any surface,,,especially any fabric, and if it contacts any painted surface it will damage that.

Without more detail I may have just added confusion, but I have been involved with that substance for a long time.

Answer 3

If is is high temp hot glue than yes it will melt it. If it is low temp hot glue then you should be okay. I assume you are talking upholstery foam.

Answer 4

Use a water based spray adhesive to attach fabric, cotton batting or wood to the foam. This is what all furniture makers use.
